Solve the dust suppression efficiency low problem when concentrate warehouse material feeding is distributed to production system.

[0010] 4. The utility model discloses the atomization device converts the water after filter into dry, smoke spray of 1~10um of particle diameter, when dry fog and dust particle contact, collide, make dust particle mutually stick, condense and grow, make it sink under the gravity of itself, thereby reach the effect of dust suppression, dust suppression effect can reach 85~95% or above, the utility model discloses can realize remote program automatic operation simultaneously, realizes unmanned operation.

[0011] 5. Filter screen filters the impurity that can enter pipeline and dust suppression host, and high pressure spray makes dust suppression efficiency improve, and the spray dust suppression design using fine water atomization principle, and the water fog that spreads in the air produces negative ion, and combines with a large number of positive ions in dust, when fog drop particle and dust particle diameter are similar, will mutually adsorb and stick, and sink after weight gain, effectively inhibit dust diffusion, thereby reach the purpose of dust fall. Can make workshop dust index reach the national occupational health control standard.

[0012] 6. The utility model discloses adopt spray dust suppression device rotary spray combination design, effectively prevent the dust that concentrates stockyard unloading car process and screening process produces, solved the problem and concentrates loss of problem of dust environmental pollution is more serious, effectively protected the environment, reduced the loss.
